Hi all,
Finally, after a 3 months wait and many broken promises, the overhauled and serviced Imacon Flextight 848 was back at the professional lab where I normally do my scanning.
I have now made some new scans for my "Ektar 100 / Film vs. Alpha 900" test on my webpage, however, it will take some time to update the webpage...
However, things are looking good and the scans are waaaay better than from the desolate "backup" Imacon 646. Not only does the overhauled scanner turn out good results for color, also the 646 is now proven to have a focussing issue as well... the 848 is much better and Ektar scans results are therefore better as well.
Anyway, back to the reason for this thread post: Going through the Flextight software settings, I noticed a setting I had overlooked before, it's called something like "Optimize" and it has tree settings:
- Quality
- Speed
- True resolution
Now I have no clue as to what these settings actually do :confused:
The only thing I could come up with, was that maybe these settings were related to "non-true-optical" resolution PPI setting. E.g. the highest 8000 PPI setting of the 848 is of course a "true-optical" resolution, but something like "5865" PPI probably isn't, and is probably interpolated.
Now my thought: Does the "Optimize" setting kick in at these "interpolated" resolutions, determining the way the interpolation should be performed?
E.g.:
- Speed: Some nearest neighbour choice of pixel value?
- True Optical: bilinear interpolation
- Quality: bicubic interpolation
Or is this assumptions just nonsense? If so, could someone please explain what these settings do with the scan results and what setting is preferred?
Thanks!
